Quotes Uncovered: Memorable Movie Lines

Two years ago, I asked for suggestions for the most memorable movie lines of recent years, to help with the next edition of The Yale Book of Quotations. Let me repeat my “bleg” from that time, and ask again for suggestions:

Now I turn to film quotes, which have probably supplanted literary quotations in cultural resonance. The American Film Institute has named the following as its top film quotes of all time:

1. “Frankly, my dear, I don’t give a damn.” Gone With the Wind
2. “I’m going to make him an offer he can’t refuse.” The Godfather
3. “You don’t understand! I coulda had class. I coulda been a contender. I could’ve been somebody, instead of a bum, which is what I am.” On the Waterfront
4. “Toto, I’ve got a feeling we’re not in Kansas anymore.” The Wizard of Oz

I have no illusions that contemporary movie lines resemble such classics in any way, but precisely for the reason that things have gone downhill in the film quote world, I bleg for assistance in identifying the most memorable cinematic quotes of the 21st century so far. Please identify the film as well as the quote.
